To all whom "it may concern Be it known that I, EDWIN T. GREENFIELD, a citizen of the United States, and resident of Kialnesha, in the countyof Sullivan and State of New York, have made a new and useful Invention in Machines for Manufacturing Paper Bottles 01' Containing Vessels, of which the following is a specification.

My invention is directed to novel mechanism for manufacturing or constructing bottles or containing vessels for liquids generally, but, particularly for dairy products, as milk, cream, etc., and it has for its object, to construct such a bottle or containing vessel from fibrous material, such as paper, and in such manner as to produce a bottle or vessel of great strength, minimum lightness and at a minimum cost.

The machine constituting the subject matter of this application is especially designed to manufacture a bottle like that disclosed in U. S. Patent No. 940,310, granted to me on the 16th day of November, 1909, the same being made from a tube of paper and so constructed that the throat and neck of the article possesses ."great strength thereby adapting it to be handled when being filled or transported from place to place as ordinary glass bottles are handled, but without danger of damage or injury thereto.

For a full and clear understanding of the invention such as will enable others skilled in the art to construct and use the same, reference is had to the accompanying drawings, in which,

Figure 1 is a part sectional, part side elevational view of complete machine in the nature of a mold for constructing the be fore-mentioned bottle, illustrating also the paper tube in position preparatory to performing the method of shaping the throat and neck of the bottle proper. Fig. 2 is a plan View as seen looking at Fig. from the top toward the bottom of the drawings, upon the assumption that the throat and neck forming parts have been forced into the position shown in dottedlines Fig. l, the clampingring shown in this figurenot heing seen in Fig. l. 8 is vertical sectional lines.

view taken through Fig. 2 on the line XX, the two positions of the clamping ring and clamping wedges for use therewith being shown respectively in full lines and dotted Fig. 4 is a perspective view of the double or duplex forming arms which successively effect the formation of the throat and neck proper of the bottle, and then the turning down of the folds of the surplus materia'l so as to, form ribs or plaits which give increased strength to those parts. Fig. 5 is a plan view of a heading tool for securing the bottom part thereof, a similar tool of smaller dimensions being provided for performing the like function with relation to the mouth ring at the upper end of the neck of the bottle; a sectional view of the body of the bottle being shown in position while the action of securing the bottom thereto is being effected. Fig. 6 is' a sectional view taken through Fig. 5 and as seen looking thereat from the bottom toward the top of the drawings in the direction of the arrows. but upon the assumption that the operating beading lever is removed to its outer or inoperative position; this view illus- 7 5 trating also the bottom ofthe bottle proper and the manner in which it is secured to the body thereof, together with the means for detachably securing it to a bench or table. Fig. 7 is a sectional view of the neck and month of the completed bottle, illustrating the manner in which the mouth ring is secured to the neck proper by a heading tool like that shown in Figs. 5 and 6.

Referring now to the drawings in detail S5 and first to Figs. 1 to i inclusive, 1, 2 and 3 represent respectively the body part, the throat part and the neck part of an interior stationary forming mold having the conformation or shape of the interior of the so bottle to be constructed, said mold being two part in eiiect; that is to say, split in the direction of its length to a point approximating the neck thereof so that the same may be spread at its bottom. 4 represents a tube made of paper or other fibrous mate rial and having substantially the interior diameter of the ext ior of the body part 1 of the mold. 5'represents the base or supporting part of the mold and 6 a wedge adapted to spread the bottom of the body part l thereof. 7, 7, represents a plurality 5 of forming arms which are provided at their bottoms with dowel pins 8, 8, adapted to fit loosely "in-radially disposed holes in the base 5,'there "being two of these dowel pins and corresponding holes for each arm. These arms are of internal curvilinear cross section at the .various parts of the length thereof to conform tothe exterior curvilinear surface of the completed bottle. 9, 9, are curvilinear parts secured to the forming arm 7, 7,

by screws, as shown, and the structural arirangement of all of these interconnected parts is such that when in closed position about the mold 1, 2 and 3, they fit snugly against the faces of all of the parts thereof,

as will be apparent on inspection of Figs. 1 v and 2. 10, 10 constitute similar curvilinear forming arms desi ed to complete the folding down of the ri s or plaits after the firstnamed arms 7, 7 andthe curvilinear parts 9, 9 have been drawn forward in the manner shown in Fig. 2. 11, 11 are pins pivotally securing the arms 10, 10 to the arms 7,7,

each pair of arms 7, 10, thus constituting in effect one set of duplex forming arms. 12 is a clamping ring designed to apply the proper pressure to the upper ends of. the

arms 7, 7, during the first step of the method and of the conformation of the bottle proper, and 18, 13 are wedges designed to complete the final step of the forming method by forcing the curvilinear forming arms 10, 10 into their ultimate position, as will be described in connection with the mode of operation.

Referring now to Figs. 5 and 6, I will describe the apparatus for completing the bottle by securing the cup like bottom to the bottom of the body part of the bottle, and also for securing the mouth ring -to the upper end of the neck. 16 represents the base of a heading tool which is constructed of steel, iron or other metal, and 17, 17. are holes therethrough for detachably securing this tool to a bench or table through the agency of pins 18, 18,18. 19 represents a curvilinear bead forming part with a groove 20 in its exterior cylindrical surface, said' bead forming part having the curvature on its exterior face of the inner'surface of the tube from which the bottle is to be constructed. 21 represents the male part of the bead forming-tool having the same interior curvature as "the groove 20 and secured directly to an operating lever 22, pivotedat one end to the base 16 and provided with an operating handle 23 at the other end thereof. 24 represents a tubular cup which is conflstrllctedby forming the same in a heated die "in a well known manner to those skilled in the art of forming bbxes and like articles from paper under pressure in heated dies, said cup having the same exterior diameter as the inner diameter of the tube 4.

25 (see Fig. 7) represents the neck of the completed bottle as formed in the molds above described, and 26 the mouth ring which is constructed by heated dies, in the same manner as was the cup 24:, and is of such a nature that it may he slipped directly over the end of the neck so as to be secured thereto by a concentric head 27.

Having described the bottle proper and also the apparatus by which said bottle is constructed, I will now proceed to describe the method of-operation of forming the same. Referring first to Figs. 1 to 4 inclusive, all of the parts of the mold pro er, which are seen in Figs. 1 and 4, are rst subjected to heat in a furnace to such an extent as will not burn the paper when the mold is being used. The interior mold is then inserted within the tube 4 until the bottom thereof is flush with .the'lower end of said tube and therefore becomes a station ary mold. The wedge 6 is then inserted in the bottom of the interior mold and the parts as thus interconnected are dropped into the cylindrical opening in the bottom of the base or support 5, so that when the wedge 6 which'now rests upon the bench or table is forced forward to its limit, the tube will be firmly secured between the mold and the inner wall of said base. In this position the four arms 7, 7, 7, 7 and curvilinearparts 9, 9, 9, 9 are forced forward by the clamping ring 12, as will be apparent on inspection of Fig.2, the ring 12 being drivendown to its lowest position as seen in dotted lines Fig. 3.

The parts are allowed to stand for an instant in this position until the paper sets betgleen the parts 9, 9, :9 and the interior mo The operation so far described performs the first step in the manufacture of my novel bottle hereinafter claimed, in that it molds or forms that part of the tube lying respectively under the curvilinear parts 9, 9, 9, against the throat and neck parts of the interior forming mold, giving to themajor portion of this end of the paper tube the exact conformation-onishape of well known types of bottles having cone-shaped throats and cylindrical necks. At the same time, however, it will be noted on examination of Fig. 2, there is a surplus of the paper which 120 is squeezed out between the lateral-edges of the curvilinear parts 9, 9, 9 into the corresponding spaces. between the pivoted arms 7, 7, 7. 1 This surplus of material is in the nature of a plurality of foldsyfoursuch 125 being shown. The ring 12 is now removed 1 and the arms 7, 7 released so that thelat-p eral edges-of the curvilinear parts- 9,9 are released from behind the curvedextensions of the paper seen in Fig. 2. The wedge 6 is ew tempor r lyleesed as a to permit the bottle asthus far. formed and its sup porting mold to be rotated a fractional part of a revolution so as bring the exterior of the curvilinear portions of folds of the surplus material which are to constitute the p a ts d re tly opposite he eunviliaeanp rte 9, 9, 9, and the arts are again forced,- 052-;

my novel bottle, in that it forms a plurality of box plaits with overlapping. edges, which edges are parallel with each otherthrough- 'out the entire length of the neck, and the continuation of such edges converge from the lower end of the neck to the lower end of the throat or the upper end of the body portion of the bottle proper. The ring 12 and wedges 13 are now removed and the wedge 6 withdrawn from the bottom of the interior mold when the body part thereof and neck of the bottle is in completed condition' and ready for receiving the cup bottom and mouth ring to be applied thereto through the agency of the tool illustrated in Figs. 5 and 6., which 0 eration will now be described. The 'tool' il ustrated in these figures .of the drawings is first heated to approximately the same temperature as was the entire mold shown in Fig. 1 and it is detachably secured to a bench or table through the'agency of the pins 18, 18, ex-

tending through the holes 17, 17 17' in the base thereof. The cup 24 is now inserted in the interior of the bottom of the bottle as thus far formed with the bottom part up, and with the inner side'thereof resting against the curvilinear part 19 of the tool, with the bottom proper of the bottle resting firmly on the top surface of the base 16. The 0 erator then taking hold of the handle 23 o the lever 22 advances the heated male part 21 against the bottom of the bottle.-with sulficient force to form the concentric head, clearly illustrated in Fig. 6. The male part is then withdrawn and this operation repeated in sequence until a complete bead is formed around the bottom thereof which effectuallyunites the same to the lower part of the body proper. This part of the operfirst set of said arms formin throat of the bottle proper with intervening ofthe bottom thereto. The mouth .26 is now slipped over the neck of the. filin the manner shown in Fig. 7 and a concentric head 2'? is formed therearound in theme manner as the like bead Was formed around the bottom and with a like tool of smaller, dimensions.

This operation just described constitutes the fina .s en of hat. .tr sa 9r; shame of the bottle and, as thus ormed 1t 1s subjected .to a bath of molten parafiin or an equivalent water-proofing agent, which effectually seals all of the parts together and renders the body and I throat parts thereof practically transparent.

I do notlimit my invention to the specific details of construction hereinbefore described and disclosed in the accompanying drawings for manufacturing bottles from paper or analogous fiber by forming the throat in plaits and securing the bottom and mouth ring thereto in the manner described, as a number of the,features thereof might be materially departed from and still come within the scope of .my claims hereinafter made. Nor do I claim in this appli-' cation the method of making a bottle of paperor analogous fibrous material as hereinbeforedescribed, as this feature constitutes the subject matter of United States Patent No. 1,016,327 granted to me on the 6th day of February, 1912.
